Struts2 : TypeConverter and Null Values

[Sami Dalouche <sk...@free.fr>]

Hi,

Let's consider we have a S2 select box that is not required (s:select
required="false" ).

The property to which it is bound can be null. However, by default,
Struts2 complains using the invalid field error message.

One way to circumvent this would be, I guess, to use some
NullSafeTypeConverter, associated to the java.lang.Object type.

Several questions :
1] Is this the best approach ?
2] Why doesn't Struts ship NullSafeTypeConverter by default ?

Regards,
Sami Dalouche
